Sodium cumene sulfonate

Sodium cumene sulfonate (CAS 32073-22-6, EC 250-913-5) is an aromatic sulfonate salt supplied under trade names including NAXONATE SC, NAXONATE 45SC, Manro SCS 93, and Cyclophil SCS40. It carries no assigned E-code and is commonly abbreviated as SCS in formulation and procurement contexts.

In textile and leather processing, SCS functions as a hydrotrope, reducing the surface tension of aqueous systems to improve dye penetration and distribute active ingredients evenly across fiber substrates. In agricultural formulations, it acts as an emulsifier and dispersant, stabilising pesticide concentrates and improving the spreadability of active compounds on plant surfaces.

Sodium cumene sulfonate is available in liquid and solid grades, with typical active-matter concentrations ranging from 40% to 93% depending on the supplier grade. It is subject to REACH registration requirements within the EU. Procurement teams should confirm grade-specific documentation, including safety data sheets and certificates of analysis, prior to sourcing.
